59. Tracking Generator Feedthrough, HP 8594EM Option 010

Procedure

1.Connect the Type N cable between the RF OUT 50 ￿ and INPUT 50 ￿ connectors on the EMC analyzer. See Figure 2-84.

2.Press 4PRESET5 on the EMC analyzer, then wait for the preset routine to ￿nish. Set the EMC analyzer by pressing the following keys:

4FREQUENCY5 300 4MHz5

4SPAN5 0 4Hz5

4BW5 IF BW AUTO MAN (MAN) 30 4kHz5

4MKR5

4AUX/USER5 Track Gen

SRC PWR ON OFF (ON) 102 4dB￿V5

3.On the EMC analyzer, press TRACKING PEAK . Wait for the PEAKING message to disappear.

4.Connect the CAL OUTPUT to the INPUT 50 ￿.

5.Set the EMC analyzer by pressing the following keys:

4SPAN5 10 4MHz5

4AMPLITUDE5 REF LVL 87 4dB￿V5

ATTEN AUTO MAN (MAN) 0 4dB5

4MKR !5 MKR ! HIGH

4MKR5 More 1 of 3 MK TRACK ON OFF (ON)

4SPAN5 100 4kHz5

Wait for the AUTO ZOOM message to disappear, then set the EMC analyzer as follows:

4BW5 AVG BW AUTO MAN (MAN) 30 4Hz5

4MKR5 More 1 of 3 MK TRACK ON OFF (OFF)

6.Press 4SGL SWP5, wait for the completion of a new sweep, then press 4MKR !5

MKR ! HIGH .

Subtract the MKR amplitude reading from 87 dB￿V, then enter the result in the EMC analyzer as the REF LVL OFFSET. For example, if the marker reads 86.79 dB￿V, enter +0.21 dB.
